What are you talking about, that's completely reasonable.

That seems like an entirely reasonable response in isolation. Sometimes you write new software and find it just doesn't work in production. Were they not doing anything else to prevent money laundering?

Or "We wrote some software to prevent money laundering but it worked properly and blocked heaps of profitable transactions, so we turned it off"
